How many input combinations would a truth table have for a five input AND gate?
This number grows exponentially at 2n, where n is the number of inputs. So, a 4-input AND gate has 16 possible combinations, 5 inputs would be 32 outputs, and so on.
How many inputs can an OR gate have?
Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
How many 2 input OR gates are needed to implement 4 input OR gate?
The number of 2-input NAND gates required to implement a 2-input XOR gate is 4.
| Logic Gates | Min. number of NOR Gate | Min. number of NAND Gate |
|---|---|---|
| OR | 2 | 3 |
| EX-OR | 5 | 4 |
| EXNOR | 4 | 5 |
| NAND | 4 | 1 |
How many combinations of 3 inputs are there?
We would expect there to be 256 logically unique expressions over three variables (2^3 assignments to 3 variables, and 2 function values for each assignment, means 2^(2^3) = 2^8 = 256 functions).
How many combinations are handled in a LUT?
A real 5-LUT can perform 232 different functions (each of 32 input combinations can make one of 2 outputs).
What is the truth table of OR gate?
Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate. OR Gate: An OR Gate is an electronic circuit that gives a true output (1) if one or more of its input are true. (+) is used to show the OR operation.
What is the truth table of NOT gate?
The Logic NOT Gate Truth Table
| Symbol | Truth Table | |
|---|---|---|
| Inverter or NOT Gate | A | Q |
| 0 | 1 | |
| 1 | 0 | |
| Boolean Expression Q = not A or A | Read as inverse of A gives Q |
How many 3 input gates are there in IC?
A three-input gate has eight possibilities (000, 001, 010, 011, 100, 101, 110, and 111) for input states. This increase in the number of possible input states obviously allows for more complex gate behavior.
What is or gate truth table?
The OR gate is a digital logic gate that implements logical disjunction (∨) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.
How many combinations can a truth table have?
There can be 2N input combination in the truth table of a logic system having N input binary variables.
